Abstract
In many sulphide smelters operating problems that occur in the hot end of the furnace gas system are among the msot serious in the facility. Perhaps the most troublesome is severe build-up that frequently leads to shutdown of the smelter. The unique prperties of smelter gases and dusts make these problems mroe severe in sulphide smelting than in other metallurgical processes. Smelter gas systems must be designed with an awareness of the build-up potential and the down downtime that can be incurred. A number of case studies are used to illustrate the technical issues involved in the design of smelter off-gas systems with a foucus on the problem of build-up.
